Unauthorised vehicle keys
If a non-authorised vehicle key has been inserted in the ignition lock it can be removed as follows:
•m/k/a995MKVehicles with a DSG dual clutch gearbox: press the lock button in the
selector lever and release. Pull the vehicle key out of the ignition lock.
•m/k/a995MKVehicles with a manual gearbox: remove the vehicle key from the ignition
lock.
Emergency start function
Use the emergency start function if no valid vehicle key is detected in the vehicle interior. A
corresponding display will appear in the instrument cluster. This could be the case, for example, if
the button cell in the vehicle key is weak or discharged:
•Depress and hold the brake pedal.
•Hold the vehicle key to the right of the steering column trim directly after pressing the starter
button ⇒ Fig. 120.
•The ignition is switched on automatically, and in some cases the engine is started.
Emergency deactivation
If the engine cannot be switched off by pressing the starter button briefly, an emergency switch-off
procedure is required:
•Press the starter button twice within a few seconds or press and hold once.
•The engine switches off automatically ⇒.
Immobiliser malfunction
A message will be displayed in the instrument cluster if an unauthorised vehicle key is used or there
is a fault in the system. The engine cannot be started. Use an authorised vehicle key or seek expert
assistance.
Start/stop system

The start/stop system automatically switches the engine off when the vehicle is coming to a stop
and when stationary. When required, the engine restarts automatically.

First read and observe the introductoryinformation and safety warnings⇒
Introduction
In vehicles with a 12-volt vehicle battery in the luggage compartment, there is a jump lead
connection point (positive terminalyf ⇒ Fig. 216⊕ under a cover in the engine compartment for
connecting the red jump lead.
The vehicle can be jump-started or be used to jump-start another vehicle only via this jump lead
connection point.

solid metal part which is securely bolted onto the cylinder block, or the cylinder block itself.
The discharged 12-volt vehicle battery must be properly connected to the vehicle's electrical
system.
The vehicles must not touch. Otherwise electricity could flow as soon as the positive terminals are
connected.
Ensure that the battery clamps have good metal-to-metal contact with the battery terminals.
If the engine does not start immediately, switch off the starter after about 10 seconds and try again
after about a minute.
If the engine still does not start, seek expert assistance.
Connecting jump leads (vehicles with 12-volt battery in the engine

The jump leads should only be connected in the order A – B – C – D⇒ Fig. 217.
The black jump lead should never be connected to the negative terminal (–yf R Q W K H Y R O W Y H K L F O H

12-volt vehicle battery in the vehicle electronics.
•Switch off the ignition in both vehicles ⇒ Starting and stopping the engine.
•Open the cover on the 12-volt vehicle battery in the engine compartment, if a cover is installed

Tow-starting or towing
Introduction
This chapter contains information on the followingsubjects:
⇒ Notes on tow-starting and towing
⇒ Fitting the rear towing eye
⇒ Fitting the front towing eye
⇒ Fitting the front towing eye (R-Lineyf
⇒ Driving notes when towing
Tow-starting is where a vehicle is started from it being set in motion by a vehicle that is hitched up
to it.
Towing is where a vehicle that cannot be driven is pulled away with the aid of another vehicle.
Observe any legal requirements when towing or tow-starting.
For technical reasons, vehicles with a discharged 12-volt battery must not be towed.⇒ Jump
starting
Vehicles with Keyless Access must only be towed with the ignition switched on.
Towing a vehicle when the engine is switched off and the ignition is switched on discharges the 12-
volt vehicle battery. Depending on the charge level of the 12-volt vehicle battery, the drop in voltage
can be large enough after just a few minutes that electrical consumers in the vehicle will no longer
function, e.g. the hazard warning lights.
Jump starting the vehicle incorrectly can cause the 12-volt vehicle battery to explode,
which can lead to serious injuries. Please observe the following in order to reduce the risk
of the 12-volt vehicle battery exploding:
•All work on the 12-volt vehicle battery and the electrical system can cause serious
chemical burns, fire or electric shocks. Always read the warnings and safety
information before carrying out any kind of work on the 12-volt vehicle battery ⇒ 12-
volt vehicle battery.
•Always wear suitable eye protection and gloves and never lean over the 12-volt vehicle
battery.
•Attach the connector cables in the correct order – the positive cable first, followed by
the negative.
•Never connect the negative cable to parts of the fuel system or to the brake lines.
•The non-insulated parts of the battery clamps must not be allowed to touch. The jump
lead attached to the positive terminal on the 12-volt vehicle battery must not touch
electrically conductive parts of the vehicle.
•m/k/a995MK Vehicles with battery in the engine compartment: check the battery
window on the 12-volt vehicle battery. Use a torch for this if necessary. If the display is
light yellow or colourless, do not jump start the vehicle. Seek expert assistance.
•Avoid electrostatic discharge in the vicinity of the 12-volt vehicle battery. The explosive
gas emitted from the 12-volt vehicle battery could be ignited by sparks.
•Do not carry out jump starting if the 12-volt vehicle battery is damaged or if it is or has
ever been frozen.
WARNING
Once the vehicle has been successfully jump-started, go to a qualified workshop and have
the 12-volt vehicle battery checked.
NOTICE
•Open the Vehicle settings menu in the Infotainment system.
•Touch the Tyres function button.
•Touch the SET function button.
•When all four tyre pressures correspond to the required values, touch the Confirm function
button.
After an extended driving time with driving at different speeds, the system will automatically learn
the new values and monitor them.
•If the tyre pressures have been changed.
•If one or more wheels have been changed.
•If the wheels have been swapped round, e.g. from front to rear ⇒ Rotating wheels front to rear.
The Tyre Pressure Loss Indicator stops working if there is a fault in the ESC or ABS ⇒ Brake
support systems.
After a warning about the tyre pressure being too low, switch the ignition off and then back
on again. The Tyre Pressure Loss Indicator can only then be re-synchronised.

The Tyre Pressure Monitoring System (TPMSyf P R Q L W R U V W K H W \ U H S U H V V X U H R I W K H I R X U Z K H H O V Z K L O H
the vehicle is in motion using pressure sensors on the tyres. The system warns the driver in the
event of a pressure loss.
Display of tyre pressures on the instrument cluster
Open the menu Vehicle status in the instrument cluster display ⇒ Instrument cluster. The vehicle
is displayed with the target and actual pressures of all the wheels ⇒ Fig. 234.
When the ignition is switched on, the last measured tyre pressures will be displayed first; these
values will be updated when the journey is started. If the tyre pressure is too low, the respective
actual values and the affected tyres will be marked ⇒ Fig. 234.
If the tyres are in rest state, the sensors will not transmit any tyre pressures. This stops the sensor
batteries discharging.
If no tyre pressures are transmitted, the last received values are shown in grey.
Switching the Tyre Pressure Monitoring System on and off
Observe any country-specific legal requirements for the Tyre Pressure Monitoring System.
If a set of tyres is fitted to the vehicle where the tyres either do not have wheel sensors or have
wheel sensors that are not compatible with the vehicle, the indicator lamp will flash for
approximately one minute and then light up steadily. The tyre pressures will not be monitored. The
system cannot be switched off.
Adjusting the tyre pressure
Following any relevant change in the vehicle load, the tyre pressure must be checked and altered
as necessary. The tyre pressures recommended for the vehicle are on a sticker on the driver door
pillar or on the inside of the tank flap ⇒ Tyre pressure.
